CDL Tanker Endorsement Practice Exam

The term that describes the movement of liquid in partially filled tanks is "surging." This phenomenon occurs when the liquid shifts toward one side of the tank or another due to motion—whether from acceleration, deceleration, or turning of the vehicle. Surging can create significant challenges for drivers, as it affects the stability of the tanker truck, altering the vehicle's handling and potentially leading to loss of control if not properly managed. Understanding surging is crucial for safe tank transport because it highlights the importance of driving techniques and vehicle control when dealing with liquid cargo. Proper training in managing the effects of surging can help mitigate the risks associated with transporting liquids in partially filled tanks. This concept is particularly relevant for drivers seeking a CDL Tanker Endorsement, as it ensures they are prepared for the dynamic forces at play when transporting liquid loads.
